As a fellow Y Combinator company, we’ve always admired Dropbox and loved their product. From the moment we met the founders, it was clear we shared a common goal. By combining forces with their amazing team, we can leverage the technology and scale of their platform and focus on what matters — delivering an incredible photo experience to over 100 million people.

So what happens next? First and foremost, don’t worry — your photos are safe! Though we won’t be accepting new signups, existing users can continue to use Snapjoy to share and enjoy photos just as you do now. We’ll be in touch with more information over the coming weeks.

Snapjoy currently provides its customers with a photo library stored in the cloud, so it’s a natural fit with Dropbox’s more expansive options. Dropbox has been pushing its customers to store their photos with the service, understanding that when a customer puts photos somewhere, that customer is more likely to stay and become attached.

The companies are both alumni of Y Combinator — Dropbox is one of the most profitable alumni of the startup incubator, and Snapjoy just went through the program in the summer of 2011.
